TAILBOARD SCRAPER.

Application filed July 6,

This invention relates to tail board scrapers for leveling or scraping roads and the like, and embodies certain improvements in Patent N 0. 1,343,097, issued to me June 8th, 1920.

More specifically stated, the present invention has for its object the provision of a road scraper wherein the shoes are attached to the same to permit said shoes to be quickly and conveniently attached to or removed therefrom as the occasion may require, the invention residing in the construction, combination and arrangement of parts as claimed. In the drawings forming part of this application, like numerals of reference indicate similar wherein:

Figure 1 is a side elevation. Figure 2 is a fragmentary front elevation. Figure 3is a view of one of the reinforcing I strips for the end members of the scraper.

Figure 4 is a similar view of one of the oes. V Referring to the drawings in detail, the scraper embodies arear wall made up of a centrally arranged board 10, and upper and lower boards 11 and 12 respectively, the'latter mentioned boards being. arranged at an angle to the board as clearly illustrated in Figure 1. These boards are secured together and reinforced by metallic straps 13, while the body of the scraper also includes spaced end members 14, the forward edges of which are preferably curved as illustrated. These end members 14 are provided with bores in each of which isarranged a' bolt 15, the bolts being extended through the back wall and reinforcing straps 13 and secured thereto by nuts 16. q of each end member is strengthened by a curved reinforcing strap or band 17, the lower end of which is offset as at 18 and secured to the scraper blade 19, while the upper end of this band terminates to provide a threaded extension 20 which also passes through the rear wall and has a nut 21 associated therewith. The bolts 15 above referred to are passed through these reinforcing straps or bands 17 and have their heads countersunk in openings 22 formed in said stra Eiich band 17 supports a shoe indicated at 23 in Figure 4, and it is the purpose of the parts in the several views, and- The forward edge 1925. Serial No. 41,793.

present invention to provide a construction whereby these shoes can be conveniently associated with or removed from the without disturbing any of the bolts 15. For this purpose, each reinforcing strap 17 is formed with an extension 24 which projects from one longitudinal edge of the strap, between the ends thereof, and this extension is provided with spaced openings 25 which are adapted to coincide or register with openings 26 formed in the shoes 23. This shoe is of uniform width throughout its length, the width being equal to the combined width of the strap 17 and its extension 24, so that when the shoe is arranged upon scraper and at a point approximately midway the straps as shown in Figure 2, suitable 1 fastening elements can be passed through the openings 25 and 26 above referred to. Consequently. when it is necessary to change the shoes on the scraper, it is only necessary to remove two fastening elements 27in order to separate the shoes from the scraper, as'the shoes are not otherwise connected with the structure, in which respect the present invention materially differentiates from the structure'shown in the patent above referred to.

lVhile it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of What is claimed.

Havingthus described the invention, I

7 claim:

In a scraper of the character described, a body comprising a back, end members projecting forwardly therefrom and having curved edges, metallic bands covering said edges and terminally secured to said back, a lateral extension projecting from one side edge of each band and having ings therein, a curved, shoe supported by said band and having openings arranged at one side of the longitudinal center thereof to register with the openings of said extension, and fastening elements passed through said aligned openings for securing the shoe to the extension.

In testimony whereof I aflix my signature.

GEORGE SWAIN SPREYER.
